Summary

This Phase 3 trial tests whether adding the experimental drug Rina-S to standard care (bevacizumab or monitoring) can help keep platinum-sensitive ovarian cancer from returning after chemotherapy. About 528 participants will receive either Rina-S alone, Rina-S plus bevacizumab, bevacizumab alone, or monitoring only. The study measures how long the cancer stays under control and overall survival.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Rinatabart sesutecan (Rina-S) and bevacizumab
What this could lead to
If successful, this could offer a new maintenance option to help keep platinum-sensitive ovarian cancer from returning after chemotherapy.
What could go wrong
This is an early-stage Phase 3 trial, so results are not yet proven. Side effects from Rina-S or bevacizumab may occur, and the combination may not improve outcomes over standard care alone.

Key Inclusion Criteria: * Must have histologically or cytologically confirmed high-grade serous or endometrioid epithelial ovarian cancer (EOC), primary peritoneal cancer, or fallopian tube cancer. * Must have PSOC defined as progressive disease \> 6 months (ie, 183 days) from the last dose of primary (first-line \[1L\]) platinum therapy. * Participants with known breast cancer (BRCA)-mutated (somatic or germline) or homologous recombination deficiency (HRD)-positive ovarian cancer who achieved complete response (CR)/no clinical evidence of disease (NED) or partial response (PR) following 1L platinum-based chemotherapy regimen must have previously received PARPi maintenance therapy as part of their 1L treatment. * Must have completed platinum-based chemotherapy in the 2L treatment for recurrent PSOC. * Must be randomized no later than 8 weeks from the last dose of the 2L platinum-based therapy. * Participants must have achieved a CR/NED, PR; or SD permitted only if bevacizumab was given in 2L in combination with platinum-based chemotherapy, as assessed by the investigator, following completion of 2L platinum-based chemotherapy. Key Exclusion Criteria: * Participants with clear cell, mucinous, or sarcomatous histology, mixed tumors containing any of the above histologies, or low-grade/borderline ovarian tumors * More than 2 prior lines of systemic therapy. * Progression while on or following 2L platinum-based regimen prior to randomization. * Participants who receive an intervening systemic anticancer treatment (excluding bevacizumab) after the last dose of 2L platinum-based chemotherapy and prior to randomization.
